Study on prediction and assessment of durability of concrete bridges

Many concrete bridges have different degrees of durability problem for the effects of loads and bad environment. For the goals of reducing or avoiding the serious consequences from deteriorating of durability, a evaluation method for bridge´s durability is need. This method need to find out the durability situation of concrete bridges timely and will not cost much to monitor the bridges. It analyzes the prediction and assessment of durability of concrete bridges in summary, on this basis it points out the current prediction and assessment of durability of concretes bridge limitations, and proposes countermeasure solving the limitations. Namely the factors that effecting the durability of concrete bridge are studied and summarized, and then a three-layer evaluation model for durability of concrete bridge is built base on the fuzzy evaluation theory.
